Application led January 8, 1913. Serial No. 740,777.

To all whom it' may concern:

Be it known that l, Jol-IN J. TA'rUM, a citizen of the United States, residing in the city of Baltimore, in the State of Maryland, have invented certain new and useful lmprovements-'in Carllools, of which the fol.- lowing is a specification.

It is a well known fact that the roof sheets of outside metal car roots have a back and forth movement relatively to the body of the car when the car is in motion. This movement is called weaving and is greatest in a direction lengthwise of the car. As al result of such movement of the roof sheets therunning board saddle, which commonly rests on the roof sheets, but which is bolted fast to the ,substructure of the roof, wears oil the protective covering o'l paint and ultimatelyv rusts holes in the roof sheets near the ridge of the roof. 5X-,fracture of the roof sheet at that point, through which rain, snow and dust majY pass intothe interior of the car, is Concealed by the running board saddles and is likely t0. remain unobserved until the ladiner inthe car is damaged, thus resulting in claims for damages against the railroads. Furthermore, a sheet thus worn at the ridgeP end is a total loss, as it must be thrown away, notwithstanding the 'balance of its area is uninjured.

The principal object of my invention is to arrange the root' sheets upon the car in such wav1 asto eliminate all liability of the main roof sheets becoming damaged bv chating` ot the running board saddles. Further objerts are to provide, means tor securing the root sheets loosely along both their eaves and ridge margins, and to reduce the cost olf maintenance and cost o'l repairs ot car roofs to a minimum. TWith these and other objects in view my invention consists in the. novel parts and combinations oli parts hereinafter described, and is more 'lullj7 pointed out in the claims.

For the purpose of illustrating and describing mv improved roof. l have shown it applied to a car having side posts 1, side sheathing Q and side plates 3. The roof substructure comprises the carlines it, the wooden rool sheathing and thefascia boards -t which are secured on the side sheathing` at thc eaves ot the car and which have their lower edges thickened to protect the root sheets and flashing` from side swipin;r and corncring. f,

The main rooting sheets 7, which are not as long as the standard rootingl sheet now in use. are rebent along their outer or eaves ends into parallel planes on their under sides to 'form hooked flanges S, the edges 0 of which are doubled under and terminate back from the eaves of the. car as more clearly seen in Fig. 3, 'The doubled edges oi. the flanges space the latter above the eaves llashine'` and act as water sheds to direct water and ldirt toward the arves ot the car instead ot. its catching in the pockets formed by the hooked flanges.

Het-alflashing strips l() are nailed at one edge to the fascia thence bentover the eaves to cover the joint between the side bodv ot the flashing to torni a hooked flange and itsedge l2 doubled in the same manner as the, edges ot the root sheet rlanges. 'The flashing is hooked` into the flanges on the eaves ends oiE the roof sheets and secures them loosely upon the car along the eaves line. The doubled edges 3 and l2 prevent moisture and dirt from creeping along the sheets 7 to strain or buckling,

flashing and roof sheets and also act as spacing members between the sheets and flashing. It will be not ed that the joint between the roof sheets and the flashing is short of the eaves of the car and that the roof sheets are thereby protected from injury by sideswiping.

The side marginal edges of the roof sheets are flanged up` and rebent, as shown in Fig. 4, so as Ito interlock and form a flexible watertight joint or seam between adjacent sheets.

The ridge or inner ends of the fmain roof sheets are rebent into parallel planes spaced above the sheets to form hooked flanges 13, the edges of which are doubled under to form water sheds 14. The ridge roof sheet 15 extends from end to end of the car either in a single strip or preferably in overlapping sections. It is bent up intermediate its ends to form ltransverse inverted channel shaped hoods 16 which register with and straddle the flexible seams of the side marginal edges of the roof sheets, said hoods being of greater inside width than said marginal seams whereby the seams may vmove freely within the hoods when the roof is distorted or the roof sheets are weaving.

The longitudinal margins of the ridge roof sheet 15 are rebent into planes parallel to and under the adjacent portions thereof, forming hooked flanges 17. The edges 18 of these flanges are doubled under as shown in Fig. 2. The flanges 13 on the inner ends of the roof sheets hook into and interlock With the marginal flanges of the lridge sheets, thereby forming a flexible water tight joint between the roof sheets 7 and the ridge roof sheet 15. It is evident that the main roofsheets 7 can move crosswise and lengthwise on the roof substructure when the car is weaving without subjecting the as .they have at their s1de marginal edges and at their eaves and ridge ends. In other words, the sheets 7 are free to float on the roof substructure but at the same time they are securely fastened to the car.

The ruiming board saddles 19 are arranged on top of the ridge roof sheet 15 over the hoods 16, each being provided with a longitudinal groove in which said hood cnters. The end, spaces between the sidesi`ot' the hoods 16 and the flexible seams 21 of the main roof sheets are closed against entrance of water and cinders by means of hobd ca ps 22. This hood cap is provided with side wings 23 having openings 24 in which are fixed the ends of a bolt 25 passing through the end of the running board saddle, thereby loosely securing the hood cap to the end of the ruuning board saddle. -The lower edges of the caps extend below the saddles in close proximity to the rooting sheets 7, and are proflexible joints vided with notches 26 constructed to fit snugly over the seams 21 of said rootl sheets. e hood caps and bolts 25 are free to slide with the roof sheets 7 transversely oftheends of the saddles, thereby enabling them to have `a snug fit with the seams 21, and maintaining the tight closure of the open ends of the hoods 1 As shown in the the saddle 19 is equal to the width of the ridge roof sheet 15, 'and it is supported thereon and does not come in contact with the main roof sheets 7. The running board saddles 19 carry the running boards 20 and are rigidly secured to the car at the ridge in any well known manner. v

A car roof-embodying my invention is flexible at the ridge as well asat the eaves and there is no liability of the running board saddle cutting through the main roof sheets, whereby the life of the roof is materially prolonged.

The possibility of the running board saddles cutting through the ridge roof sheets is extremely remote as there is practically no relative movement between them; however should this happen repairs can be made quickly and at a small expense as compared with the expense of replacing the relatively wide and long main roof sheets 7, inasmuch las it would only be necessary to replace the comparatively narrow ridge roof sheets 15.

Although I have illustrated and described what I consider to be the best form of my invention, I do not desire to limit myself thereto, as it is evident that modifications may be made in the constructional details thereof.

What I claim is:

1. A car roof including sheets terminating short of the. eaves and short 'of the ridge, a ridge sheet secured upon the substructure at the ridge and extending beyond each side of the ridge, said ridge sheet having underturned flanges along its side margins. loosely interlocking with the ridgeend of the roof sheet, said flanges limiting the movement of the roof sheets from the ridge, and means movably connecting the eaves ends of the roof sheets to the roof substrmfture, whereby the root` sheets are limited away from the eaves and are free to. move sidewise and diagonall \Y at both top and bot separate roof as to endwise movement,

drawings they length of i toni ends at the same time, when the car body is weaving.

2. A carroof comprising a series of main roof sheets having hook shape end flanges,

flexible seams connecting said sheets at their.'

side ma rgiual edges, eaves flashing strips havthe hook shaped ridge flanges of said main roof sheets at the ridge ends thereolC and secured to the substructure whereby the main roof sheets are limited as to endwise movement toward the eaves and are free to move sidewise and diagonally at both eaves and vridge ends at the saine time, When the ear is Weaving. Y

3. In a car roof the combination with a series of movable roof sheets connected to gether at their side marginal edges by upstanding iiexible seams, oiu a fixed ridge roof of said saddles whereby they may move longitudinally with said seams.

Il. In a Car roof the combination with a running board saddle of a cap slidably mounted on the end of, the saddle and provided with a notch constructed to receive a roof seam with which it interloeks.

5. In a car roof, the combination of transverse roof sheets connected by upstanding side marginal seams, a roof sheet extending along the ridge, runningf board saddles supported on said ridge roof sheet, said running board saddles having grooves in their under sides adapted to embrace said upstanding seams, and Caps loosely mounted 011 the ends of said running board saddles covering the ends of said grooves.
